Raman spectroscopic characteristics of phthalocyanine and naphthalocyanine in sandwich-type (na)phthalocyaninato and porphyrinato rare earth complexes

摘要

The Raman spectroscopic data for a series of 50 phthalocyaninato and/or porphyrinato rare earth complexes including monomeric Tb[T(4-Cl)PP]acac, and sandwich-type RE(Pc')(2) [RE = Ce, Eu, Gd, Tb, Y; Pc' = Pc, Pc(OC5H11)(8), Pc(OC8H17)(8), Pc(C7H15)(8)], RE(Nc*)(2) [RE = La, Ce, Pr, Nd, Eu, Gd, Tb, Er, Y; Nc* = Nc(Bu-t)(4), Nc(SC12H25)(8)], (Pc)RE(Pc*)RE(Pc*) [RE = Eu, Tb, Er; Pc* = Pc(OC5H11)(8)], (Pc)Eu(Pc*)Er(Pc*) [Pc* = Pc(OC8H17)(8)], Eu(Pc)(Pc*) [Pc* = Pc(OC5H11)(8), Pc(C7H15)(8)], Eu(Por)(Pc') [Por = TPP, TPyP, T(4-Cl)PP, T(4-OMe)PP, T(4-'Bu)PP; Pc' = Pc, Pc(C7H15)(8)], Eu(Por)(Nc) [Por = TPyP, T(4-Cl)PP], HE-u(Por)(Pc), Ce(TPyP)(Pc), RE2(Por)(2)(Pc) [RE = Ce, Eu; Por = TPP, TPyP, T(4-Cl)PP, T(4-'Bu)PP], and RE2(Por)(Pc')(2) [RE = Eu, Ce, Y; Por = TPP, TPyP, T(4-Cl)PP, T(4-OMe)PP, T(4-'Bu)PP, OEP; Pc' = Pc, Pc(OC8H17)(8), Pc(C7H15)(8)], and (TPyP)RE(Pc*)RE'(Pc*) [RE not equal RE' = Eu, Y; Pc* = Pc(C7H15)(8)] have been collected in the solid state using a Raman microprobe and excitation at 632.8 nm (and in some cases, 780 nm). The Raman characteristics for unsubstituted and substituted (na)phthalocyaninato mono-radical anions Pc'(.-) (Pc' = Pc, Pc*), Nc*(.-) and dianions Pc'(2-) (Pc' = PC, Pc*) are thus comparatively described. The intense band at ca. 1500 cm(-1) was confirmed to be the marker band for Pc'(.-) and Pc'(2-) anions. (C) 2000 Elsevier Science Ltd. All rights reserved. [References: 65]
